Trying to install a OS on our new servers. However there is no CD-ROM.

I have the ISO and a USB stick. bit of goggling offers a few programs, which do you recommend that doesn't come with nasty bits of malaware attached ?

Definitely Rufus!

 

The latest version also enables you to create NTFS-formatted USB flash drives for installing Windows from that boot on UEFI PCs which usually only support FAT32-formatted flash drives.

 

This generic bootloader, which is primarily intended for use with Rufus, is meant to allow seamless booting from an EFI bootloader, that resides on an NTFS partitions. In other words, UEFI:NTFS is designed to remove the UEFI restriction of being able to natively boot from FAT32 only, and allow NTFS boot without the need for any user intervention.

 

This can be used, for instance, for booting an USB Windows NTFS installation media, in EFI mode, allowing support for files that are larger than 4GB (something a native EFI FAT32 partition cannot support), or allow indiscriminate EFI or BIOS boot of Windows To Go drives.

 

The way this works, in conjunction with Rufus, is as follows:

 

  1. Rufus creates 2 partitions on the target USB disk (these can be MBR or GPT partitions). The first one is an NTFS partition occupying almost all the drive, that contains the Windows files (for Windows To Go, or for regular installation), and the second is a very small FAT partition, located at the very end, that contains an NTFS EFI driver (see http://efi.akeo.ie) as well as the UEFI:NTFS bootloader.
  2. When the USB drive boots in EFI mode, the first NTFS partition gets ignored by the EFI firmware and the UEFI:NTFS bootloader from the bootable FAT partition is executed.
  3. UEFI:NTFS then loads the relevant NTFS EFI driver, locates the existing NTFS partition on the same media, and executes the /efi/boot/bootx64.efi or /efi/boot/bootia32.efi that resides there. This achieves the exact same outcome as if the EFI firmware had native NTFS support and could boot straight from NTFS.

If I recall correctly, for current versions of Windows (2008/7 and up), so long as the USB drive is NTFS formatted and formatted as a bootable device, you can just drag and drop the iso contents to the USB. I'm sure I did this with Server 2012R2 when I upgraded our storage system over Easter.
